Hello.
I have very simple question: What are Mg II and Mg I. Mg is chemical symbol for Magnesium and I believe Greek number next to Mg should indicates ionization state of element. Could you tell me which ionization Mg I indicates and also Mg II?
Hello. Let's say time tsi = 10 s, electric field strength Esi = 10 V/m in SI unit. In order to convert these to those in atomic system of units, I think right procedure is that tat =...
